Earth Science for Kids: Rocks, Rock Cycle, and Formation

Melted rock or magma is sent to the earth''s surface by a volcano. It cools and forms an igneous rock. 2. Next the weather, or a river, and other events will slowly break up this rock into small pieces of sediment. 3. As sediment builds up and hardens over years, a sedimentary rock is formed. 4.

There are different types of sedimentary rocks

Igneous rock (derived from the Latin word ignis meaning fire), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava.

Types of Rocks | Classification of Rocks.

Three different types of Igneous rocks are thus formed: (a) PLUTONIC : Formed at great depths, generally from 210 km below the surface. These have coarse crystals. Examples: Granites, Syenites'', Gabbros. (b) HYPABYSSAL: Formed at the intermediate depth below the surface generally up to 2 km. These have mixed characters.

10(d) Composition of Rocks

Sedimentary Rocks - formed by burial, compression, and chemical modification of deposited weathered rock debris or sediments at the Earth''s surface. Most rocks are composed of minerals.Minerals are defined by geologists as naturally occurring inorganic solids that have a crystalline structure and a distinct chemical composition.

How Are Metamorphic Rocks Formed?

 · Metamorphic rock is formed under extreme heat or pressure. Unlike other types of rock, metamorphic rocks start as rocks which are then transformed into different rocks. Metamorphic rocks are classified as either foliated or non foliated depending on their mineral structure and pattern. Metamorphic rocks are rocks that have changed from one type ...
